If you need to change a channel’s sampling interval, you must first find out which group the channel is associated with.
In Firmware versions that are older than 2.3x, two default groups, Group 1 and Group 2, are provided. Channels do not need to be in a group in order to sample.
In Firmware version 2.3x and newer, six default groups, called Group 1...6, are provided. Serial and analog channels must be in a group, or they will not sample. For details about digital channels and groups, see Digital Channel Advanced Configuration.
To discover a channel’s association with a group:
- In the left pane, click Devices.
- In the Sites Tree pane, click the device name.
- In the right pane, click the Configuration tab. The Stream Management table is displayed. Make sure that Data Streams is selected in the top right drop-down box.
- In the Stream Management table, the group that the channel is associated with is listed in the Sample Group column. For example, a value of 1 indicates that the channel is associated with Group 1.
